This'l invention relates to an improvement in tire chains. and is designed to provide an i-licient device of this character. which can readily he attached and removed and which is so arranged that the parts which are suhjccted to the greatest wear lcan readily he re placed. Another object ot my invention ls to provide a device of tlnscharacter having` two traction chains connected to each other and which are oppositely disposed,y with Ifelation to each other so that there 'is no tend?i cnpy i for the device .to creep laterally oi Iti'ansi enselv with relation to the tire.

A` further object oi' my invention isto .so connect the traction chains to the securingr chains that the traction chains will he maintainedV in their proper relation to the securiliLr chains when removed from the wheel.

still further object of my invention is to provide a non-skid device' in which the traction chain or chains have a spring connectionvith the wheel and which is so ar ranged that such connection is relieved of a. considerable portion of the weight of the tractionfchain or chains. 4 I

compnnying drawings which will now be described. it being premised, however, that Patented May 25, 1920.

var-ions changes may be made in the details of construction and the general arrangement -of the parts, without departing from the spirit and sco f of my invention as defined in the appended claims.

ln these drawings the reference character E3 designates the tirepof a wheel, and 3 the fell;7 thereof. A In the drawings I have show n a cushion tire, although it will readily be.

appreciated that the device ma. be attached to `a pneumatic tired wheel. li device comprises traction chains 4, the ends oi which are secured to a link member 5, and as shown in., Fig. as well as Fig. 1, the chains i are wisted reversely with relation to each other. l,The link member 5 is formed of a single piede of wire bent vu on itself to form eyes t5 to -which the end inks of the chains 4 are attached and the eye for the reception Vof a securing chain 8. The ends of the wire lfrom which the link 5 is made,

are lient upon each other, as clearl shown in Figs. 3 and 4 and are sptwel ed at the points S). t )ne end of the securing chain 8 is passed through' the eye 7 of the link 5, and "the end thereof isprovided with a. hook member 1U which is adapted to be connected to any of the intermediate links, aS shown in Fig. 2. in order to draw the traction chain about the tire 2. Connected to one of the links of the securingr chain 8 and between1 the links 5 when the device is in position, an S-shaped locking member 11 which is arranged to hrevent the end of the chain 8 from passing: through one of the links and prevent the traction chains from becoming disengaged from the securing chain. The other end of tlnrsecnrinnr chain is connected to one end oi a spring member 12 which is in turn connected to a flexible member 13' which is adapted to surround the hub of the the springs 12 tothis extent. This enables4 lighter springs to he employed and Haves wear and hreakage oi' the springs.

he anti-skid from the wheel it is i vent the end of the securing chain from passing through the right end link 5 as seen in Fig. 2. By this arrangement it will readily be seen that the chain parts are always in their proper positions to be applied `to the wheel; and if the hook mem er l() on any one of the chains should be diseng'a ed from its link the locking member 1l w' prevent the traction chain from slipping.v olf the end of the securing chain.

In Figs. 5, 6 and 7 I have shown a device similar to that shown in the other figures with the exception that there is only one ,traction chain fwvhich is provided with link members at. each end for the reception of the securing chain 8a. Intliis device vthe locking member' 1l.u consists of a tubular member of rubberorA any other material which Vis slipped over the chain and will prevent it from passing .through the eyes of one'of the links 5a. In this construction I haveshown a roller 20 on each of the link members 5* about which the securing chains ss. The advantages of my invention result :from the provision of a traction or non- `skid device in"which the traction chains are slidably connected to the securing chainin sucha manner that the securing chain may be ad'usted to draw the traction chains tant a lit the wheel, together with aV spring member for holding theY traction chain in tension. Another adyanta e results from th'e revision of a traction c ain having two 65am members which are oppositely dis posed with rclat'on one will oppose the other' and prevent creeping. A :further advantage results from the provision of a lookin member on the securing chain .which wi permit a free 'movement of the securin `chain with relation to the traction chain or adjustment, but pre nt one end of the traction chain from sliptiin off the securing chain.

Af sti l further advantage of my inv intion results from the arrangement Where i the wheel felly is caused to carry a considerable part of the weight of the traction chain or chains.

I claim:

1. A device of the character destribed, comprising a traction chain adapted o ass around-the tire of a wheel, a securin c ain arranged to lass through links on bot ends ot ,the traction chain, means for connecting oneiend of the securing chain to an interme diwtiportion lhereof, and means for securto each other, so tluitl 'as descri c -to -a common link member, Will ing the other end of the securing chain to the wheel. f

2. A device of the character described,

arranged to pass through links on both ends' of the traction chain, means for connecting one end of the securing chain to an intermediate portion thereof, a locking member on the securing chain for preventing one end of the traction chain from slipping oli' of the securing chain, and means for securing the other end of the securing chain to a Wheel.

et. The combination of a wheel and a plurality of non-skid devices, each comprising a traction chain, of a securing chain passing through the ends of the traction chain, means on each securing chain for connecting one end thereof to an intermediate portion of the securing chain, and a resilient connection between the other end of the securing chain and the wheel. v

5. A device of the character described, comprising a plurality o non-skid devices each comprising a traction chain, the respective ends of said chains being secured to a common link member, a securing chain passing through said link members, means for connecting one end of the securing chain to an intermediate ortion thereof, and means for connectin t e opposite end of the securingbclain to t e wheel, substantially 6. A device of the character described, comprising a plurality of non-skid devices each comprisin spective ends o said chains being secu-red a securing cham. passing through said link members, means oriconnecting one endof the securing chain to an intermediate `portion thereohand a resilient connection between the op osite end of the securing chain and the w eel,zsub stantially as described.
